Terrific! Better than Khan Academy! BY FAR the most clear and concise Organic Chemistry videos on the web. (This is how I felt about Tyler Dewitt’s youtube channel for Gen. Chem.)
My only wish for the videos is that the volume was louder. It was sometimes hard to hear.
(Just a head’s up – as of 3/9/15 – the Summary of Resonance (2) link seems broken).
Thanks! And keep them coming! (Perhaps with louder audio, please).
